How to increase request timeout in IIS?

Question

How to increase request timeout in IIS 7.0? The same is done under application tab in ASP configuration settngs in IIS 6.0. I am not able to find the asp.net configuration section in IIS 7.0

Answer 1

In IIS >= 7, a <webLimits> section has replaced ConnectionTimeout, HeaderWaitTimeout, MaxGlobalBandwidth, and MinFileBytesPerSec IIS 6 metabase settings.

Example Configuration:

<configuration>
   <system.applicationHost>
      <webLimits connectionTimeout="00:01:00"
         dynamicIdleThreshold="150"
         headerWaitTimeout="00:00:30"
         minBytesPerSecond="500"
      />
   </system.applicationHost>
</configuration>

For reference: more information regarding these settings in IIS can be found here. Also, I was unable to add this section to the web.config via the IIS manager's "configuration editor", though it did show up once I added it and searched the configuration.

Answer 2

To Increase request time out add this to web.config

<system.web>
    <httpRuntime executionTimeout="180" />
</system.web>

and for a specific page add this

<location path="somefile.aspx">
    <system.web>
        <httpRuntime executionTimeout="180"/>
    </system.web>
</location>

The default is 90 seconds for .NET 1.x.

The default 110 seconds for .NET 2.0 and later.

Answer 3

In IIS Manager, right click on the site and go to Manage Web Site -> Advanced Settings. In there, under Connection Limits you should see Connection Time-out.

Answer 4

Add this to your Web Config

<system.web>
    <httpRuntime executionTimeout="180" />
</system.web>

Optional TimeSpan attribute.

Specifies the maximum number of seconds that a request is allowed to execute before being automatically shut down by ASP.NET.

This time-out applies only if the debug attribute in the compilation element is False. To help to prevent shutting down the application while you are debugging, do not set this time-out to a large value.

The default is "00:01:50" (110 seconds).

Answer 6

Use the below Power shell command to change the execution timeout (Request Timeout)

Please note that I have given this for default web site, before using these please change the site and then try to use this.

 Set-WebConfigurationProperty -pspath 'MACHINE/WEBROOT/APPHOST/Default Web Site'  -filter "system.web/httpRuntime" -name "executionTimeout" -value "00:01:40"

Or, You can use the below C# code to do the same thing

using System;
using System.Text;
using Microsoft.Web.Administration;

internal static class Sample {

    private static void Main() {

        using(ServerManager serverManager = new ServerManager()) { 
            Configuration config = serverManager.GetWebConfiguration("Default Web Site");

            ConfigurationSection httpRuntimeSection = config.GetSection("system.web/httpRuntime");
            httpRuntimeSection["executionTimeout"] = TimeSpan.Parse("00:01:40");

            serverManager.CommitChanges();
        }
    }
}

Or, you can use the JavaScript to do this.

var adminManager = new ActiveXObject('Microsoft.ApplicationHost.WritableAdminManager');
adminManager.CommitPath = "MACHINE/WEBROOT/APPHOST/Default Web Site";

var httpRuntimeSection = adminManager.GetAdminSection("system.web/httpRuntime", "MACHINE/WEBROOT/APPHOST/Default Web Site");
httpRuntimeSection.Properties.Item("executionTimeout").Value = "00:01:40";

adminManager.CommitChanges();

Or, you can use the AppCmd commands.

appcmd.exe set config "Default Web Site" -section:system.web/httpRuntime /executionTimeout:"00:01:40"
